[1] Green Lung began by playing to small audiences in local public houses, building a following in part due to activity on Instagram[2] From here, the band's first signing was with German independent label Kosmic Artifactz, with whom they released their first EP, Free the Witch in 2018, and then their first LP Woodland Rites in March 2019.

This latter release saw significant critical acclaim within the relevant specialist press, with Rich Webb of Distorted Sound magazine describing it as "simply incredible"[3] and Dave Knowles of Metal Temple calling it an "instant classic".

[5] Vocalist Tom Templar said at interview that the band chose Svart over an unidentified larger label, calling them the "last bastion of music industry good".

[7] The band signed with Nuclear Blast Records in July 2022,[1] before playing a set at Damnation Festival in November, again to positive coverage including from Kerrang!

[9][10] Green Lung's musical style has been described as drawing heavily from British classic rock and early heavy metal, with Queen, Deep Purple and especially Black Sabbath's 1970s material cited as audible influences by reviewers.
